The only use of base_attr_group and hubless_base_attr_group is to pass
their addresses to sysfs_create_group() and sysfs_remove_group(), both
which takes pointers to const attribute_group structs. Make them const
to allow the compiler to put them in read-only memory.

Add the uv_sysfs driver to construct a read-only sysfs interface at
/sys/firmware/sgi_uv/ to expose information gathered from UV BIOS. This
information includes:
* UV Hub descriptions, including physical location
* Cabling layout between hubs on the fabric
* PCI topology, including physical location of PCI cards
Together, the information provides a robust physical description of a UV
system, useful for correlating to performance data or performing remote
support.
